Saint Catherine's Monastery was built by Emperor Justinian to protect the site of the Burning Bush and the monks who had gathered there. Its collection of icons and manuscripts constitutes one of the most important holdings of early Christian art and texts in existence.
Origin Story
The monastery's origins lie in the encounter recorded in Exodus. Moses, tending sheep near Mount Horeb, saw a bush that burned but was not consumed. God spoke from within the bush, revealing the divine name 'I AM WHO I AM' and commissioning Moses to lead the Israelites from Egypt. Moses removed his sandals because he stood on holy ground.
Christian monks recognized that the Burning Bush prefigured the Virgin Mary, who bore divine fire in Christ without being consumed. The site attracted hermits from the 3rd century onward. Empress Helena ordered a chapel built at the Burning Bush in the 330s. By the 6th century, a community of monks had settled here permanently.
Saint Catherine of Alexandria was a learned noblewoman martyred in the early 4th century. According to hagiography, angels carried her body to the highest mountain in the Sinai, where monks discovered her incorrupt relics around 800 CE. The monastery was rededicated in her honor, and portions of her remains are displayed in the basilica today.

Spiritual Lineage
Saint Catherine's participates in the lineage of desert monasticism that began in Egypt in the 3rd century. The desert fathers and mothers who fled the cities to seek God in the wilderness established a tradition that Saint Catherine's continues. The monastery's architecture follows Byzantine patterns, and its liturgical practice maintains ancient Alexandrian forms. Its manuscripts connect it to the broader Christian manuscript tradition, while its isolation preserved texts and icons that were lost elsewhere.
